# $ bitbake core-image-minimal

# 2. How to install selenium on Ubuntu:

# 3. How to install selenium addon in firefox:
# Download the lastest firefox addon from http://release.seleniumhq.org/selenium-ide/
# Then install it. You can also install firebug and firepath addon

# 4. How to start writing a new case:
# All you need to do is to implement the function test_xxx() and  pile it on.

# 5. How to test with Chrome browser
# Download/install chrome on host
# Download chromedriver from https://code.google.com/p/chromedriver/downloads/list  according to your host type
# put chromedriver in PATH, (e.g. /usr/bin/, bear in mind to chmod)
# For windows host, you may put chromedriver.exe in the same directory as chrome.exe
